Technical field
This utility model is related to a kind of higher desulfurization slurry ph sampling and measuring device of solid content, is mainly used in coal-burning power plant
Wet process of FGD field.
Background technology
Coal-burning power plant's Wet Flue Gas Desulfurization Technology mainly adopts limestone one gypsum at present, in flue gas desulfurization course,
In absorption tower the control of desulfurization slurry ph value be to ensure that desulphurization system efficiency and desulphurization system safety, economical operation key because
Element.Existing general desulfurization slurry ph value on-line measurement mode mainly has direct method (insert glass electrode in serosity and measure) and takes out
Follow the example of and (absorbing, reflux is installed by tower wall, produces gravity flow using the serosity discrepancy in elevation in absorption tower, allow serosity flow into reflux
In, then glass electrode is inserted in reflux and measures).
Because containing calcium sulfate, calcium sulfite, Calcium Carbonate and other solid particulate matter in desulfurization slurry, slurry solid content exists
15% about, and desulfurization slurry is in high flow velocities state in absorption tower, so when ph meter measures serosity ph using direct method
When, in desulfurization slurry, big solid particulate matter can produce big abrasion to ph measuring electrode, has a strong impact on the use longevity that ph counts electrode
Life.
Though big solid in serosity can be reduced using extraction method inscribe the abrasion that grain thing high speed washes away ph glass electrode probe, slurry
Little particle in liquid can stick on electrode probe within a very short time, is also easy to produce ph value, the electrode that can not accurately measure serosity
Probe needs frequent clean thus the problems such as cause electrode probe to damage.
Therefore, design a kind of device of serosity ph in on-line measurement desulfuration absorbing tower, fundamentally solve desulfurization slurry and exist
Measure the adverse effect that ph is counted during ph with electrode probe, and be conducive to extending the service life of ph meter and reduce power plant
The workload that operations staff safeguards to ph meter.
Content of the invention
The purpose of this utility model is to provide a kind of device of serosity ph in on-line measurement desulfuration absorbing tower, overcomes desulfurization
The impact to ph sampling and measuring process for the different size of solid in serosity, extends the service life of ph meter and improves ph measurement
The accuracy of value.
The technical solution of the utility model is, using action of gravity with adopt on the basis of absorbing existing extraction method advantage
Carry out solid-liquid separation twice with filtering material, be finally reached the removal adverse effect to ph glass electrode probe measurement for the solid.
In a kind of on-line measurement desulfuration absorbing tower, the device of serosity ph is divided by water intaking valve, water inlet pipe, solid-liquid separation case, solid-liquid
From device, ph measurement apparatus, baffle plate, blowoff valve and outlet pipe composition.
Described solid-liquid separator is arranged on the afterbody of solid-liquid separation case, and the opening of solid-liquid separator stretches out solid-liquid separation case；
Described ph measurement apparatus are made up of ph glass electrode probe and ph digital display instrument；Described ph glass electrode probe is inserted in described solid-liquid
In separator；The output lead of described ph glass electrode probe connects described ph digital display instrument；The front upper of described solid-liquid separation case
It is provided with water intaking valve and water inlet pipe；Upper rear is provided with blowoff valve；The bottom of described solid-liquid separation case is provided with outlet pipe；Institute
The front position stating the inside of solid-liquid separation case is provided with two pieces of baffle plates.
Described ph measurement apparatus be by be inserted into solid-liquid separator with steady pin ph glass electrode probe and with ph number
Aobvious instrument composition, ph measured value can be sent to desulfurization dcs control system by described ph digital display instrument；Ph digital display instrument is placed in solid-liquid separation
Outside case.
The twice baffle plate of setting in described solid-liquid separation case fore-end, allows the desulfurization flowing into solid-liquid separation case through water inlet pipe
Serosity slows down, and is flowed when twice baffle plate so that the solid in serosity is precipitated to bottom by turning back, thus realizing starching
The solid-liquid separation of liquid.
The afterbody that described solid-liquid separator is located in solid-liquid separation case, is with externally threaded porous cylindrical body, cylinder
Outer wrapping has the filter cloth filtering tiny solid function.Operations staff find filter cloth life-time service occur blocking be difficult to permeable
When, easily solid-liquid separator can be disassembled from solid-liquid separation case and filter cloth is rinsed or changes.
The beneficial effects of the utility model are that this device provides a kind of dress of serosity ph in on-line measurement desulfuration absorbing tower
Put, the impact to ph sampling and measuring process for the different size of solid in desulfurization slurry can be overcome, extend the service life of ph meter
With the accuracy improving ph measured value, mitigate the maintenance workload that operations staff counts to ph.
The on-line period measurement of this utility model serosity ph be applied to coal-burning power plant's wet desulphurization absorption tower is it is also possible to join
Examine the serosity ph sampling and measuring higher for other solid contents.
